Python 贪吃蛇游戏代码示例 - 简单易懂

当然！以下是一个简单的贪吃蛇游戏的 Python 代码示例：

import pygame
import random

# 游戏窗口大小
WINDOW_WIDTH = 640
WINDOW_HEIGHT = 480
GRID_SIZE = 20
GRID_WIDTH = WINDOW_WIDTH // GRID_SIZE
GRID_HEIGHT = WINDOW_HEIGHT // GRID_SIZE

# 颜色定义
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 蛇类
class Snake:
    def __init__(self):
        self.body = [(GRID_WIDTH // 2, GRID_HEIGHT // 2)]
        self.direction = (1, 0)

    def move(self):
        head = self.body[0]
        x = (head[0] + self.direction[0]) % GRID_WIDTH
        y = (head[1] + self.direction[1]) % GRID_HEIGHT
        new_head = (x, y)
        self.body.insert(0, new_head)
        self.body.pop()

    def change_direction(self, direction):
        if (direction[0] * -1, direction[1] * -1) != self.direction:
            self.direction = direction

    def grow(self):
        tail = self.body[-1]
        self.body.append(tail)

    def check_collision(self):
        head = self.body[0]
        for segment in self.body[1:]:
            if segment == head:
                return True
        return False

# 食物类
class Food:
    def __init__(self):
        self.position = (random.randint(0, GRID_WIDTH - 1), random.randint(0, GRID_HEIGHT - 1))

    def respawn(self):
        self.position = (random.randint(0, GRID_WIDTH - 1), random.randint(0, GRID_HEIGHT - 1))

# 游戏类

        pygame.init()
        self.window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
        self.clock = pygame.time.Clock()
        self.snake = Snake()
        self.food = Food()
        self.score = 0

    def handle_events(self):
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

                elif event.key == pygame.K_LEFT:
                    self.snake.change_direction((-1, 0))
                elif event.key == pygame.K_RIGHT:
                    self.snake.change_direction((1, 0))

    def update(self):
        self.snake.move()

        if self.snake.body[0] == self.food.position:
            self.snake.grow()
            self.food.respawn()
            self.score += 10

        if self.snake.check_collision():
            self.game_over()

    def render(self):
        self.window.fill(WHITE)
        for segment in self.snake.body:
            pygame.draw.rect(self.window, GREEN, (segment[0] * GRID_SIZE, segment[1] * GRID_SIZE, GRID_SIZE, GRID_SIZE))
        pygame.draw.rect(self.window, RED, (self.food.position[0] * GRID_SIZE, self.food.position[1] * GRID_SIZE, GRID_SIZE, GRID_SIZE))
        pygame.display.set_caption(f'Snake Game (Score: {self.score})')
        pygame.display.update()

    def game_over(self):
        pygame.quit()
        quit()

    def run(self):
        while True:
            self.handle_events()
            self.update()
            self.render()
            self.clock.tick(10)

# 启动游戏
game = Game()
game.run()

这个代码使用了 Pygame 库来实现游戏窗口和绘图功能。你可以在运行代码之前确保已经安装了 Pygame 库。

这只是一个简单示例，你可以根据自己的需要对其进行扩展和改进。祝你编写出一个有趣的贪吃蛇游戏！
